e1000e: 82579 performance improvements
The initial support for 82579 was tuned poorly for performance. Adjust the
packet buffer allocation appropriately for both standard and jumbo frames;
and for jumbo frames increase the receive descriptor pre-fetch, disable
adaptive interrupt moderation and set the DMA latency tolerance.
